Bits

Yikes. Been a while. I can’t think of anything intelligent to blog, so some linky tidbits instead:

rpm 4.10 includes “~” as a special versioning character, just like dpkg has for ages. Holds a special place in my heart since I did the original patch for dpkg a bit over 11 years ago now. (And looking at that bug history now, it appears it was accepted for my birthday a year later, awww). “ls” from coreutils also supports it (they borrowed the code from dpkg, based on a copyright disclaimer request I’ve finally gotten around to replying to), though I don’t think it’s actually documented.

Read a couple of interesting takes on the Facebook IPO: one from a “blue-collar hedge fund manager” (yeah, riiight), who blamed NASDAQ for not handling trades properly on opening day, then essentially forcing traders to sell their stock immediately to be compensated for trades not executed properly; and one from Nanex via ZeroHedge with an animation showing that NASDAQ was not actually making a market in Facebook stock for an extended period (claiming offers to buy for $43 and offers to sell for $42.99, but not executing them and clearing them out), screwing up the other exchanges they connect to and the high-frequency algorithmic traders that use them. To me, Google’s reverse-auction IPO that tried to ensure there wasn’t a day-one stock price “pop” just seems better all the time…

SpaceX has been doing a pretty amazing demo: correctly handled launch abort, quick turn around on fix; successful launch; successful delivery of payload to the ISS. Get it back down again, and they’ve really got something. Also impressive: per Wikipedia at least, “As of May 2012, SpaceX has operated on total funding of approximately one billion dollars in its first ten years of operation”, 80% of which has come from payments by customers (“progress payments on long-term launch contracts and development contracts”). That is, about the same amount as what Facebook paid for Instagram and its 13 employees…
